Measurement; With Automatic Temperature Compensation (Atc); Without Atc (Manual Temperature Compensation); Taking Measurements - LaMotte CON 6 PLUS Manual

4. MEASUREMENT

The meter is capable of taking measurements that incorporate
temperature measurements automatically (most common) or using a
temperature which is input manually (rare).

4.1 With Automatic Temperature Compensation (ATC)

To compensate the reading using temperature values as measured by
the electrode, attach the phono jack of the temperature sensor to the
meter. The measured reading will be automatically compensated to the
specifi ed normalization temperature (either 20 °C or 25 °C). The rate of
compensation which is applied is the Temperature Coeffi cient.
See Section 5.5 – Temperature Coeffi cient.
See Section 5.6 – Normalization Temperature.

4.2 Without ATC (Manual Temperature Compensation)

Manual temperature compensation will be applied after manually
entering the temperature value into the meter. The meter will compensate
from this fi xed value to the normalization temperature. Any temperature
can be used between 0 and 50 °C. The default value is 25 °C.
To activate the manual temperature compensation, unplug the mini phono
jack of the temperature sensor from the meter and follow the steps 2 thru
6 of Temperature Calibration.
See Section 3.6 – Temperature Calibration.

4.3 Taking Measurements

1. Rinse the probe with deionized or distilled water before use to
remove any impurities. Shake or air dry. To avoid contamination
or sample dilution, rinse the probe with a small volume of the
sample.
2. Dip the probe into the sample. Stir the sample gently with the
probe.
3. Allow time for the reading to stabilize. Note the reading on the
display.
NOTE:
• The protective probe guard must be attached during
measurement. Erroneous results will occur while the probe guard
is removed.
